Minature Roses

I happened to get the most beautiful Pink tiny Rose plant and have fallen in love with it. It the size for a balcony pot. Since I bought it 1 August, there have been 3 brand new flowers. I know NOTHING about Roses. The info that came with the plant was quite confusing. It said that it likes a South facing window (implying it is an indoor plant), but then it said that it likes temperatures 10C to 16C. Who keeps their houses that cool? So I put it on the porch in a shady place. Should I put rose food on it or anything? Are there any experts for minature Roses on this very knowledgeable message board??? If so please come forward. Thanks
